# glibmm 2.66 (this overlay's SLOT=2, i.e. gtkmm:3's old-ABI dependency;
# SLOT=2.68 is the separately-packaged glibmm-2.88) is upstream-frozen and
# predates GLib's G_DECLARE_FINAL_TYPE()-based headers for some types (see
# the patch below). With glib-2.90.0 installed, two of glibmm's generated
# giomm headers fail with "typedef redefinition with different types".
#
# Fixing that properly means patching the generated untracked/gio/giomm/
# headers directly (see PATCHES), but glibmm's own const-whoops patch
# (::gentoo's glibmm-2.66.8-r1) touches tools/m4/class_gobject.m4 instead,
# which only takes effect via -Dmaintainer-mode=true regenerating every
# header from its .hg template at build time -- which would silently
# overwrite our direct header patch. So: drop maintainer-mode entirely
# (meson then just uses the release tarball's own pre-generated untracked/
# content, which upstream ships for exactly this non-maintainer case) and
# drop the const-whoops patch along with it, since it would be a no-op
# without regeneration. It's a minor G_GNUC_CONST correctness nicety
# unrelated to this fix, not something functionally required.
